Imagine, you did the checksum on the ISO and you burned the CD, still you want to double check the integrity of the files on the CD . . . .
Here is a little script that will do the checksum on your CDs. You do need the original checksum to compare with the outcome of this script. Steps 1. Open terminal and type $ vi checkcd press "i" ( to put vi in insertmode ) 2. Type the following code in vi editor #!/bin/sh #checkcd device=$1 blocksize=`isoinfo -d -i $device | grep "^Logical block size is:" | cut -d " " -f 5` if test "$blocksize" = ""; then echo catdevice FATAL ERROR: Blank blocksize >&2 exit fi blockcount=`isoinfo -d -i $device | grep "^Volume size is:" | cut -d " " -f 4` if test "$blockcount" = ""; then echo catdevice FATAL ERROR: Blank blockcount >&2 exit fi command="dd if=$device bs=$blocksize count=$blockcount conv=notrunc,noerror" echo "$command" >&2 $command 3. Save the file with suitable name, here for example save it as "chechcd". 4. Give the read and execute permission to that file $ sudo chmod 755 checkcd 5. Execute the following command to check CD $ sudo ./checkcd /dev/cdrom | md5sum -- விஷ்ணுராஜ். க Kanchi Linux User Group Rocks ! http://kanchilug.wordpress.com My Experiments In Linux are here http://gnutuxfollower.wordpress.com _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
